Mexico made easy work of Puerto Rico on Wednesday night in the opening match of CONCACAF qualifying for the 2016 Olympic Games in a 6-0 victory from Toyota Stadium in Frisco, Texas.

Striker Maribel Dominguez recorded a hat trick in the victory as she out-shot Puerto Rico by herself, 8-6. Mexico attempted 25 shots on Puerto Rico's goal, as they simply overwhelmed their opponents. For the 37-year-old Dominguez, it was a reminder to the rest of CONCACAF that she can still play with the best of them.

She opened the scoring in the 18th minute after going through the heart of the Puerto Rican defense and playing a nice one-two with Desiree Monsivais, as NBC Sports Soccer showed:

Her second came in the 51st with Mexico up 2-0 and was even easier than her first. Dominguez, who was basically unmarked, received a low cross from Arianna Romero and slotted it in with no issues to put Mexico up 3-0.

A six-goal output will most likely see them lead the group unless the United States manage to put up seven goals against Costa Rica later on Wednesday night. This kind of start to their qualifying will give Mexico plenty of confidence moving forward, as they are in a tough group.

The United States are coming off a Women's World Cup triumph in the summer of 2015, and Costa Rica were a team that made the tournament and fared better than Mexico. Costa Rica put up two points in the group stage, while Mexico could only muster one.

For Puerto Rico, they are the unfortunate minnows in a very difficult Group A. Puerto Rico have only played in one major tournament ever, which was the group stage of the 1998 Gold Cup, where they allowed 38 goals in three games.
